From HB Racing:
The HB Racing molded nylon rear wings are very close to a same weight as lexan wing, with the added durability of molded nylon. Large side dams and 2 inner plates add stability, and a wicker bill helps tune downforce to track conditions. The new wicker bill design eliminates the need for nuts for extra weight savings.

Also included are four pairs of dimples molded into the bottom of the wing to make mounting simple when using the popular HB one-piece wing mounts, and the dimples give racers 4 fore/aft mounting position choices. These wings are IFMAR legal (40mm width x 50mm height square area for car identification numbers) and the side dams can be easily trimmed to meet ROAR rules.
